77de753f65 Improve self-relocation:
o  We don't expect the PLT relocations to follow the .rela section
   anymore. We still assume that PLT relocations are long formed,
o  Document register usage,
o  Improve ILP,
o  Fix the FPTR relocation by creating unique OPDs per function.
   Comparing functions is valid now,
o  The IPLT relocation naturally handles the addend. Deal with it.
   We ignore the addend for FPTR relocations for now. It's not at
   all clear what it means anyway.

Fix ABI misinterpretation:
o  For Elf_Rela relocations, the addend is explicit and should not
   be loaded from the memory address we're relocating. Only do that
   for Elf_Rel relocations (ie the short form).
o  DIR64LSB is not the same as REL64LSB. DIR64LSB applies to a
   symbol (S+A), whereas REL64LSB applies to the base address (BD+A),

2ab188f529 Finally fix loader completely for IA64. efifs_stat() wasn't setting
the S_IFREG bit for regular files.  This caused the path search code to
skip it when it finally did find the kernel (after the common/module.c
buffer overrun bug was fixed)

5459842c5e Do not assume that ${OBJCOPY} variable exists. It was hidden by the

a6d81d83a2 Fix self hosted loader building. When you use a self configured gcc, it
detects and uses the gas section merge support.  As a result, a whole bunch
of new sections arrive, including .rodata.str1.8, which was not included
in our custom ldscript.ia64.  The result was a loader binary that EFI
rejected.

While here, collect the loader shell commands linker set and include it
in the data area rather than having its own section.

/boot/loader.efi was the last holdout for having a 100% self built ia64
system.

c459265de7 Pass the physical address of the bootinfo block to the kernel in
register r8. We continue to write the bootinfo block at the same
hardwired address, because the kernel still expects it there.
It is expected that future kernels use register r8 to get to the
bootinfo block and don't depend on the hardwired address anymore.

Bump the loader version once again due to the interface change.

a918e110c4 Add a quick and dirty way to determine where we're loaded from. We
only care if it's network or not at this time. If we're loaded from
the network, we set currdev (=loaddev) so that the kernel is loaded
from the network as well. In all other cases we initialize to disk.
This makes netbooting more convenient and can easily be enhanced to
do more elaborate checking.

4e357dbc58 The EFI loader has been improved a lot since it was first added.
Most significantly (from an interfacing point of view) is the
support for the FPSWA pointer passing. Even though that was added
4 months ago, it's probably not a bad idea to bump the version
number to reflect this.

7608f7cb80 Fix the initialization of the protocol:
o  Query the state field of the protocol mode to determine whether
   we need to start and/or initialize the protocol. When we're
   loaded across the network, the protocol has already been started
   and is already initialized. When no networking has happened yet,
   we have to start and initialize the protocol ourselves.
o  After initialization, we have to set the receive filters. Not
   doing this results in a deaf interface. We set the unicast and
   broadcast filters. Multicast may not be supported. This specific
   change fixes the problem we had that we could not netboot if
   the loader was started from the EFI shell.
o  To help future debugging, add a function that dumps the current
   mode of the interface. It's conditional on EFINET_DEBUG.
o  To help in runtime problems, emit a diagnostic message when we
   could not initialize the protocol properly.

c61a2c84f0 Don't blindly dereference f->f_devdata as if it's always a pointer to
an efi_devdesc structure. When we're netbooting, f->f_devdata holds
the address of the network socket variable. Dereferencing this caused
some very unpredictable behaviour, including proper functioning.
So, as a sanity check, we first make sure f->f_dev points to our
own devsw. If not, the open will fail before we use f->f_devdata.

This solves the netboot hangs I invariably got whenever I used the
latest toolchain to compile the EFI loader.

9423456018 o Make efinet_put a blocking call by waiting for the protocol
layer to signal transmission of the packet. This resolves the
   problem I'm seeing that an immediate call to net->Receive
   after calling net->Transmit returns EFI_DEVICE_ERROR. This
   condition seems to be sufficiently persistent that BOOTP and
   RARP fail.
o  While here, unify all functions to have 'nif' defined. Some
   have it as arguments. The others now have them as locals. We
   now always get the protocol interface by using the 'nif' var.

The current status of netbooting is that even though we now reliably
have BOOTP working (again), opening a file (ie loading a kernel)
across the network causes the loader to hang. I'm working on that now.

de76c8189e Remove bootinfo.bi_kernel. It isn't used by the kernel. struct bootinfo
should go away on ia64, we should be loader metadata based since that is
the only way we can boot (loader, skiload).

0ac2d551f2 o Add new header <sys/stdint.h>.
o Make <stdint.h> a symbolic link to <sys/stdint.h>.
o Move most of <sys/inttypes.h> into <sys/stdint.h>, as per C99.
o Remove <sys/inttypes.h>.
o Adjust includes in sys/types.h and boot/efi/include/ia64/efibind.h
  to reflect new location of integer types in <sys/stdint.h>.
o Remove previously symbolicly linked <inttypes.h>, instead create a
  new file.
o Add MD headers <machine/_inttypes.h> from NetBSD.
o Include <sys/stdint.h> in <inttypes.h>, as required by C99; and
  include <machine/_inttypes.h> in <inttypes.h>, to fill in the
  remaining requirements for <inttypes.h>.
o Add additional integer types in <machine/ansi.h> and
  <machine/limits.h> which are included via <sys/stdint.h>.
